Title: Method for joining metallic bodies
IPC: B23K35/00
Filed: 1941-05-23
Abstract: 547,755. Brazing parts of vacuum tubes &c. STANDARD TELEPHONES & CABLES, Ltd. May 23, 1941, No. 6635. Convention date, July 13, 1940. [Classes 83 (ii) and 83 (iv)] In brazing together two pieces of metal, such as the copper parts of a vacuum tube of the electron discharge type prior to heating to a high temperature to effect degasifying, the pieces are first each coated with a thin film of a metal with which the brazing material has a lower rate of alloying than with the metal of the pieces, placing the coated pieces in close proximity, heating to brazing temperature and applying brazing material. The coating ensures the capillary flow of brazing material completely between the pieces instead of soaking into the pieces adjacent the point of application of the brazing material and thus renders the joint gas tight. Copper pieces may be coated with nickel or iron and the brazing material may consist of silver solder containing 70 per cent of silver and 30 per cent of copper. A pair of two inch copper discs may be electrolytically coated with nickel for five minutes at a rate of 20 amperes per sq. ft. current density. The parts are then placed together leaving a space not exceeding 0.002 inch and preferably 0.001 inch and the silver solder applied round the periphery and the parts heated for 2-5 minutes at brazing temperature which may be from 100-300‹ C. in excess of the melting point of the silver solder. Brazing may be effected in the presence of fluxes such as borax or fluorides or in an atmosphere of hydrogen. The silver solder may alternatively be deposited as one or more globules in one of the parts prior to assembly. A wire 8 of silver solder may be held at the joint between a pair of closed nickel plated copper tubes 6, 7 by a corrugated spring clip 9 consisting of a wire of an alloy which does not melt at the brazing temperature such as a nickel-chromium alloy. Two apertured discs 10, 11 to be brazed to a tube 12 have their apertures flared to leave a space to receive a wire 13 of silver solder, the parts being previously nickel plated.

Patent GB-833326-A (GB)
Title: Improvements relating to control means for machine tools
Inventor: CHATTERTON GEORGE
IPC: B23Q35/12
Filed: 1955-03-08
Abstract: 833,326. Copying - machines. CRAVEN BROS. (MANCHESTER) Ltd. June 4, 1956 [March 8, 1955], No. 6756/55. Class 40 (1). [Also in Groups XXII, XXXV and XXXIX] In a copying-machine in which the position of the cutting tool is determined by signals from a feeler co-operating with a pattern to control the operation of a pair of reversible D.C. motors, the signals act via two transductors having, in the embodiment described, power windings 5, 6 in the arms of bridge rectifiers feeding the motors. As shown, when the feeler is out of contact with the pattern, contact 19 is closed and a relay TA is energized to energize a forward or reverse contactor relay FA, RA, FB, RB associated with motor MA or MB in accordance with the position of a manually operated selector switch A-F. With the illustrated setting, relay FB pulls up and completes a balanced bridge circuit formed by resistors 15 ... 17 and the armature of motor MB. A first control winding 7 of each transductor normally receives current from a potential source 14 and biases the transductor to give its minimum output. Before the motor is connected up, however, the effect of this winding is neutralized by that of a second control winding 8 which also receives current from the source 14 in the direction 11 to 12. When the motor is connected up, the maximum output is therefore applied to it to cause it to start rapidly. As the back E.M.F. builds up, the potential of point 11 is reduced in relation to that of the junction of 15, 16; the current through 7 is increased, and that through 8 reduced or reversed, to reduce the output of the transductor until a stable condition is reached dependent on the position of the slider of the potentiaL divider 13. The output of the transductor is limited by a further winding 34 which receives current dependent on the voltage drop in resistor 17 through which the motor is fed. When the feeler reaches the pattern, contact 19 is opened, relay TA falls and, with the setting of the selector switch shown, relay FA operates to give a forward drive to motor MA. Further pressure on the feeler causes contacts 21 to close whereupon relay TB releases relay FA and energizes relay RB to cause motor MB to be driven in the reverse direction. Excessive deflection of the stylus operates a trip which releases relay OD to cut off the supply.

Title: Improvements in the method of controlling combustion in metallurgical, boiler and other furnaces
IPC: C21B5/00
Filed: 1932-03-08
Abstract: 398,200. Liquid, gaseous, and pulverulent fuel furnaces. BRITISH REMA MANUFACTURING CO., Ltd. and HOWDEN, P., Highroad Well, Halifax, Yorkshire. March 8, 1932, No. 6901. [Class 51 (i).] A method of controlling combustion in regenerative furnaces burning liquid, gaseous, or pulverulent fuel consists in maintaining the weight of primary air supplied to the burner at a constant value while the total weight and volume of air required for combustion is maintained at a definite ratio to the rate of fuel feed by varying the weight of secondary air when the fuel feed is varied by means of a valve or other regulating means so placed as to control the air at atmospheric temperature before it enters the regenerator. The Figure shows one form of apparatus for carrying out the above method in which fuel is fed from a hopper D by an adjustable feed device d into the primary air supplied by a fan A to the burner B. Secondary air is supplied by a fan F with a valve f arranged on its inlet or outlet side to the regenerator G and thence to the burner. A modification is described and illustrated in which fuel is supplied by a pulverizer.

Title: Electronic screening
IPC: B41M1/12
Filed: 1973-02-13
Abstract: 1448112 Copying by scanning INTERNATIONAL PUBLISHING CORP Ltd 11 Feb 1974 [13 Feb 1973] 7116/73 Heading H4F  Electronic screening apparatus generates a screened video signal representing dots, each dot being formed during a plurality of line scans, the amplitude of the received video signal being determined, either repetitively or continuously, during the formation of each dot, the screened video signal being up-dated in response to each such determination of the received video signal amplitude. In a first embodiment, Fig. 2, each dot is formed by a 4 x 16 matrix of elements (Fig. 1, not shown) the received video signal being passed to an amplitude discriminator which provides one of 60 outputs to a coding unit 2 which provides on 64 output lines the signals to produce the desired dot which are fed to four line selectors 3 (one per row of the element matrix) and thence to a row selector 4. The timing of read-out of signals from line selectors 3 and row selector 4 is controlled by a pattern controller 6, column counter 5 and row counter 7. The pattern controller 6 (also Fig. 3, not shown) may control column counter 5 so that every second row of elements is displaced by half a matrix width. Coding unit 2 may be controlled by a computer to provide different codes for different original images. Pattern controller 6 may provide different orientations for respective colour components. In an alternative embodiment, Fig. 4, a triangular waveform is derived at 31 and fed to non-linear amplifiers 32, 33, the outputs of which are added to the received video signal and passed to comparators 36, 37, a switch 38 selecting the comparator outputs depending on the portion of a dot being produced. The amplitude of the video signal may be compared with that of a triangular waveform (Fig. 5, not shown) or with that of a triangular waveform whose D.C. level is altered from a first value to a second value after one line scan and from the second value to the first value after a further two line scans; alternatively the amplitude of the video signal may be compared with the signals shown in Fig. 7 at "scan 1" and "scan 2" during successive line scans in the order "scan 2", "scan 1", "scan 1", "scan 2" for each dot. Three or more triangular waveforms may be combined for larger dots. There may be switching between triangular waveforms during a line scan and triangular waveforms may be delayed on successive line scans (Fig. 8, not shown) to produce angled screens for colour reproduction. In a further embodiment (Fig. 9, not shown) the output of a counter counting clock pulses is passed to a digital-to-analogue converter to produce a triangular waveform which is added to the received video signal and passed to a comparator; the counter output may be modified to effect, for example, tone correction.
